Product details:
Human Presenilin 2/AD5 ELISA Kit (ab277476) is an
in-vitro
enzyme-linked immunosorbent assay for the quantitative measurement of Human Presenilin 2/AD5 in serum, plasma and cell culture supernatants.
This assay employs an antibody specific for Human Presenilin 2/AD5 coated on a 96-well plate. Standards and samples are pipetted into the wells and Human Presenilin 2/AD5 present in a sample is bound to the wells by the immobilized antibody. The wells are washed, and biotinylated anti-Human Presenilin 2/AD5 antibody is added. After washing away unbound biotinylated antibody, HRP-conjugated streptavidin is pipetted to the wells. The wells are again washed, a TMB substrate solution is added to the wells and color develops in proportion to the amount of Human Presenilin 2/AD5 bound. The Stop Solution changes the color from blue to yellow, and the intensity of the color is measured at 450 nm.

The presenilin 2 (PSEN2) protein also known as AD5 plays a role as a catalytic subunit in the gamma-secretase complex. This complex is involved in intramembrane proteolysis of several type-I transmembrane proteins. PSEN2 has a mass of about 52 kDa and is expressed mainly in the brain and several other tissues throughout the body. Its gene is located on chromosome 1 and has the alternative name 'EP-2614'. Presenilin 2 is closely associated with presenilin 1 (PSEN1) a related protein within the same family.
Biological function summary
Presenilin 2 functions in the regulation of proteolytic processing of the amyloid precursor protein (APP) within the gamma-secretase complex. This action produces amyloid beta peptides which are critical for normal brain function but may accumulate under pathological conditions. The protein is also involved in NOTCH receptor activation which plays a part in cell fate determination during development. The gamma-secretase complex includes other key proteins such as nicastrin anterior pharynx-defective 1 (APH-1) and presenilin enhancer 2 (PEN-2).
Pathways
Presenilin 2 is central to the amyloidogenic pathway through its role in APP processing. This pathway links to Alzheimer's disease where dysregulation of amyloid beta peptide production leads to plaque formation. Additionally presenilin 2 takes part in the NOTCH signaling pathway which influences neurogenesis and cellular differentiation. Presenilin 1 is a partner protein of presenilin 2 within these pathways sharing overlapping functions and regulation.
Presenilin 2's connection to Alzheimer's disease arises from its role in amyloid beta production. Mutations in the PSEN2 gene can lead to familial Alzheimer's disease where altered processing of APP results in neurotoxic peptide accumulation. Additionally presenilin 2 influences cardiovascular disease development through its involvement in cell signaling pathways affecting vascular biology. Presenilin 1 mutations also associate with similar disorders due to its analogous role and participation in these pathological processes.
